javascript - 如何在 NodeJs 中修改数组中的 JSON 键名

Question

我在 NodeJS 中有一个函数，它返回一个 JSON 元素数组

let rows = function1();

这里rows看起来像：

"rows": [
    {
    "Hostname": "abc123",
    "name": "name1",
    "Status": "PASS",
    "Heading": "Not Applicable"
    },
    {
    "Hostname": "abc123",
    "name": "name2",
    "Status": "FAIL",
    "Heading": "Not Applicable"
    }
]

在这里，rows可以有任意数量的 Json 元素：

"rows": [
    {
    "Hostname": "abc123",
    "name": "name1",
    "Status": "PASS",
    "Heading": "Not Applicable"
    },
    {
    "Hostname": "abc123",
    "name": "name2",
    "Status": "FAIL",
    "Heading": "Not Applicable"
    },
    {
    "Hostname": "abc123",
    "name": "name3",
    "Status": "FAIL",
    "Heading": "Not Applicable"
    },
 ...
]

在所有 JSON 元素Hostname中将保留名称，

我想修改rows array它，如下所示：

"rows": [
    {
    "Hostname": "abc123",
    "name1Status": "PASS",
    "name1Heading": "Not Applicable"
    "name2Status": "FAIL",
    "name2Heading": "Not Applicable"
    "name3Status": "FAIL",
    "name3Heading": "Not Applicable"
     ...
]

如果你理解正确，那么你需要达到这个结果。为此使用reduce，非常方便使用数组

const rows = [
    {
    "Hostname": "abc123",
    "name": "name1",
    "Status": "PASS",
    "Heading": "Not Applicable"
    },
    {
    "Hostname": "abc123",
    "name": "name2",
    "Status": "FAIL",
    "Heading": "Not Applicable"
    }
]
const res = rows.reduce((acc, rec) => {
	let result = { ...acc, [`Hostname`]: rec.Hostname,  [`${rec.name}Status`]: rec.Status, [`${rec.name}Heading`]: rec.Heading  }
	return result
}, [])
console.log(res)
